Question

Find the distance around a circular track if it is 100 feet across. (Use 3.14 for π.)

Answer 1

The distance around a circular track if it is 100 feet across is 314 feet.

Explanation:

Circumference of circle is given by:

`C = \pi D` ....[1]

where

C is the circumference of a circle.

D is the diameter of a circle.

As per the statement:

A circular track if it is 100 feet across.

⇒
`D = 100 ft`

then

substitute this value in [1] we have;

`C = 3.14 \cdot 100`

Simplify:

`C = 314` feet

Therefore, the distance around a circular track if it is 100 feet across is 314 feet.
